Fairy tales usually have characters representing good and evil. These characters may be people, with or without supernatural powers, magical creatures and animals. Even organic and inanimate bodies (trees, flowers, books) may gained life as characters in fairy tales.
Symbolism is an important element in fairy tales. From Cinderella's glass slipper, the strong personality of Malificent, the power of love, to the nose of Pinocchio to represent what happens when someone tells a lie.
